About Your New Rosmarinus officinalis – Rosemary

Rosmarinus officinalis, now reclassified as Salvia rosmarinus, is Rosemary, an upright evergreen shrub with narrow needle-like grey-green leaves and a dense woody frame. The foliage is strongly aromatic year round, and small pale blue flowers appear over winter and into spring. Prostrate forms trail rather than stand upright.

It wants full sun and sharp drainage, and it is happier dry than wet. Established plants handle drought, salt wind and exposed positions with ease, which suits warm temperate and Mediterranean climates across southern Australia. Growth is 30 to 50 centimetres a year and maintenance amounts to an annual trim.

Rosemary is used as low hedging, in borders, as groundcover in its prostrate forms, and in herb and kitchen gardens where it is cut for cooking. It grows happily in a 40 to 50 centimetre pot by a back door. Ornamental structure and a usable crop from the same plant.

Frequently Asked Questions

About Rosemary

What is Rosemary?

Rosmarinus officinalis, now classified botanically as Salvia rosmarinus, is an upright evergreen shrub with narrow needle-like grey-green leaves and a strong resinous scent. Small pale blue flowers appear over winter and spring. The habit is woody and dense, and the aromatic foliage is held all year round.

How big does Rosemary grow?

Upright forms generally reach 1 to 1.5 metres tall and a similar width, while prostrate selections stay under 40 centimetres and spread sideways instead. Growth is around 30 to 50 centimetres a year. Regular light harvesting or trimming holds a plant well below its potential size without any harm.

Does Rosemary need sun or shade?

Full sun, without qualification. Six or more hours of direct sun gives dense growth, strong aroma and good oil content in the leaves. In shade the plant stretches, thins out and becomes prone to fungal problems. Open air movement around the plant matters almost as much as the sun does.

Is Rosemary drought tolerant?

Very. Once established it survives long dry periods on rainfall alone in most temperate districts, and it is far more likely to be killed by wet soil than by dry. Free drainage is essential. Water new plants through their first summer, then only during extended dry spells.

Can Rosemary grow in pots?

Yes, and a pot suits it well because you control the drainage. Use a pot 40 to 50 centimetres wide with a gritty free-draining mix, put it in the sunniest spot you have, and let the mix dry between waterings. A single plant on a courtyard or balcony is easy to keep.

Can I cook with this Rosemary?

Yes. Rosmarinus officinalis is the culinary rosemary, and sprigs can be cut fresh year round for roasts, breads, oils and marinades. Harvest from the soft green growth rather than the old woody stems, and take a little from several places around the bush so it keeps its shape.

How do I care for Rosemary?

Plant in full sun in free-draining soil, on a raised mound if your ground is heavy. Water sparingly once established and avoid rich fertiliser, which produces soft growth and weak flavour. Trim lightly after flowering to keep the bush dense, cutting into green growth only, since bare old wood does not reshoot.

Enriched Planting Mix (AO Certified)

$21.95

Enriched Planting Mix is a certified organic blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent, bagged in 30L. It is built to be dug through existing garden soil at planting time rather than used on its own, and the gypsum is what sets it apart from a plain compost.

Gypsum helps break up heavy clay so water and roots can move through it, while the compost and manure return organic matter and nutrient to tired ground. The coarse bark holds structure and keeps air around the root zone, and the wetting agent keeps moisture in the soil longer after rain or watering.

Use it when planting trees, shrubs, roses, fruit trees and exotic garden plants, particularly into clay. Dig a hole twice the width of the pot and 7 centimetres deeper, then mix roughly one third planting mix through the excavated soil. Spread 7 centimetres of that improved soil in the base before setting the plant in.

Frequently Asked Questions

About Enriched Planting Mix

What is Enriched Planting Mix made from?

It is a blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent. Each part has a job. The compost and manure supply organic matter and nutrient, the gypsum works on clay structure, the bark keeps air around the roots and the wetting agent holds moisture in the soil.

What plants is it suitable for?

It suits exotic garden plants, including roses, ornamental and deciduous trees, fruit trees, shrubs and perennials, and it earns its keep most on heavy clay sites. It is a planting mix rather than a potting mix, so its job is improving soil at planting time. Phosphorus sensitive natives are the one clear exception.

Is it safe for natives?

No, not for the phosphorus sensitive ones. The composted animal manure in this blend lifts phosphorus well above what Proteaceae such as Banksia, Grevillea, Hakea and Protea will tolerate, and the result can be leaf burn, dieback and plant death. Use the Native Potting Mix for those species, or plant them into unimproved local soil.

Is it certified organic?

Yes. It is a certified organic product with no chemical additives, which is why the manure and compost in it are fully composted rather than raw. That makes it sound around fruit trees and vegetable beds, and it means you are adding genuine organic matter to your soil rather than a synthetic conditioner.

How much do I need?

Work on roughly one third planting mix to two thirds of the soil you dug out of the hole. For a shrub out of a 200 millimetre pot that is only a few litres. An advanced tree going into a large hole will take considerably more. Judge the quantity by the volume of the hole rather than the size of the plant.

Can I use it in pots?

It is not a potting mix and should not be used on its own in a container. The blend is designed to be diluted through garden soil, and used straight in a pot it holds too much water and settles badly. For containers, reach for a premium potting mix, or the native mix if you are potting natives.

Does it need to be watered in?

Yes. Water the plant well several hours before you plant it, then water thoroughly again once the hole is backfilled and the soil firmed down. That first deep watering settles the improved soil around the root ball and drives out air pockets. Keep the water up over the first few months while the roots establish.
